Many large semantic systems can be described as Semantic Grids of Semantic Grids with large amounts of relatively static services and associated semantic information combined with multiple dynamic regions (sessions or subgrids) where the semantic information is changing rapidly. We design a hybrid Information Service supporting both the scalability of large amounts of relatively slowly varying data and a high performance rapidly updated Information Service for dynamic regions. We use the two web service standards UDDI and WS-Context in our system.
